So this patch is probably misnamed as nothing is QOMified here, the UIC is 
already a QOM object, what happens is rather embedding it in the SoC 
instead of only storing a reference. The advantage of embedding is likely 
that it does not have to be freed so we don't need an exit function but it 
adds a bunch of casts to other places. As said before you probably should 
do the casts once and store it in a local if you need it more than once or 
twice.
